[bug - linux-2.6.0test8]: network drops dead after putting interface in promiscuous mode

[Richard van der Veen]

Hi 

I have a problem with the test8 version of the 2.6.0 kernel. After i changed 
the network to use DHCP instead of an static network adress. I have internet 
access until i use tcpdump, ethereal or snort ... because when i do this then 
something seems to crash i have no connection at all anymore. Sometimes even 
my computer completely freezes. When that happens i only can use the reset 
button for an forced reboot.  

I use: Debian (sid)

network module: de2104x

i once tried to remove the module from the kernel and wanted to insert it 
again, hoping this maybe would help ;-). But this also resulted in a complete 
freeze of the system and i had to do a forced reset again.  The error-message 
from that crash was:
